I was speaking with a colleague the other day and he was remarking on an accomplishment I have had in my field (of microprocessor design). He assumed I had been a straight-A student all through school.
When I noted that I was far from it, he was shocked. This got me to thinking: we usually just assume that somehow grades in school (at any level) are predictors of future success, or certainly of intelligence; but I highly doubt it. I tried to find some good studies, but found five problems immediately:
- The very definition of success is elusive.
- How do you measure validity of grades?
- Most middle schools and high schools put so much emphasis on homework versus actual understanding that they are measuring behavior and compliance far more than what has been learned.
- Creativity and creative people tend to mess up metrics at each level.
- Any research I could find was done at some university which tended to bias results using university metrics of success.
